please, how do you check the excentricity for turning tools ? ( cnc, tilted saddle )
hello, i recently setup some small parts on a 250mm chuck, and for few operations i use gang/small tools; i have to align them on center pretty well, because they are fragile
i also noticed that 25mm shank tools do have the cutting edge at height 25±0.25, while i was expecting 25±0.1
please, how do you check the alignment, besides cutting a face ? i mean do you use a faster method, which does not involve cutting ? like attached things ? do you know what is their precision, are they reliable ?
image 01 : requires to have cilindrical jaws at a certain position, in order to clamp the device; such jaws should clamp without tir, at least where the bubble is located ( = downtime with jaws preparation, and jaws set-up; is faster to face-cut )
image 02 & 03 : are not for bent sleighs, but for horizontal
kindly :)

I use a 0.625'' dowel pin in the chuck or collet. Measure the tool height with a height gauge, measure the station height with gauge blocks, subtract the difference and add the pin radius, and that is the required shims to put the tool point on the spindle center line.
Then I store the dimensions on the computer with this screen in my program. Inputting the tool height and station height and clicking Apply calculates the required shims.

I found this on the internet and made one myself. If the lathe is horizontal, it works like a dream,
